Outline of Final Research Achievements

In this study, conservation units for endangered species were constructed using museum specimens, which have received little attention as genetic resources. As a result, findings related to conservation units were obtained for Aporia hippia, Thalassoduvalius masidai, Arctigalloisiana spp., and Pecteilis radiata. Genetic information was successfully obtained from specimens of Linaria japonica, Suaeda glauca, Cirsium maritimum, and Aporia hippia. In addition, I developed the methods for retaining well-preserved DNA with dried insect specimens.

Academic Significance and Societal Importance of the Research Achievements

本研究は、主に植物や昆虫などの標本における遺伝解析手法MIG-seqの有用性を検証したものである。作成や保管の状況にもよるものの、植物標本はより過去の標本からもMIG-seqに活用できることが明らかとなった。また、本研究によって絶滅危惧種の遺伝的撹乱の実態や保全単位の設定を行うことで、どの程度の人為的な移入が許容されるかについて、複数の絶滅危惧種で解明することができた。
